What Is Tether (USDT)?
Tether (USDT) is a
stablecoin—a type of cryptocurrency designed to maintain a
stable value by pegging its price 1:1 to the
U.S. dollar. This means 1 USDT is intended to always equal 1 USD. It's issued by
Tether Limited, which claims that every USDT token is backed by equivalent reserves held in cash, Treasury bills, and other assets.
USDT is widely used across the crypto ecosystem for
trading, remittances, and payments, offering users the benefits of cryptocurrency (like fast, borderless transactions) without the high volatility of typical crypto assets. It’s available on multiple blockchains, including
Ethereum (ERC-20), Tron (TRC-20), and Solana, making it highly accessible and versatile.
On BingX, you can easily buy, sell, or trade USDT with top security and 24/7 support.
How Does Tether (USDT) Stablecoin Work?
Tether (USDT) maintains a 1:1 peg to the U.S. dollar through asset-backed reserves. For every USDT issued, Tether Limited claims to hold an equivalent amount in cash, cash equivalents, or short-term U.S. Treasury bills. These reserves are meant to ensure that users can redeem 1 USDT for 1 USD at any time.
USDT is issued on multiple blockchains such as
Ethereum (ERC-20),
Tron (TRC-20),
Solana,
Polygon, and others. This allows users to transfer and use USDT across different crypto ecosystems with
fast, low-cost transactions. Because of its price stability and broad acceptance, USDT is commonly used as a
trading pair,
hedging tool, and
store of value in the crypto world.
What Determines the Price of Tether (USDT)?
Tether (USDT) is a stablecoin, so its price is designed to stay as close to $1 USD as possible. The main factor that keeps USDT at this peg is confidence in its 1:1 backing with U.S. dollar reserves. When users believe Tether Limited holds enough real-world assets to redeem every USDT token, the price stays stable.
However, short-term price fluctuations can happen due to market demand and supply, especially during high volatility in crypto markets. If demand for USDT spikes, for instance, during market crashes when traders seek stability, its price may briefly rise above $1. Conversely, if trust in its backing weakens, the price might dip slightly below $1 until confidence is restored. Arbitrage traders and large exchanges usually help bring the price back to its peg.
When Was Tether's USDT Stablecoin Launched?
Tether (USDT) was originally launched in October 2014 under the name Realcoin by co-founders Brock Pierce, Reeve Collins, and Craig Sellars. It was later rebranded to Tether to reflect its core function: “tethering” a cryptocurrency to a stable asset—namely the U.S. dollar.
Tether was built to solve one of crypto’s biggest problems:
price volatility. By issuing a token backed 1:1 by real-world assets, Tether allowed traders to move in and out of crypto markets quickly without converting back to fiat. In
2015, USDT was first launched on the
Bitcoin blockchain via the Omni Layer, and later expanded to other blockchains like
Ethereum, Tron, and Solana to improve transaction speed and scalability.
Despite facing regulatory scrutiny and transparency concerns over the years, Tether has remained the largest and most widely used stablecoin, with a market cap exceeding $144 billion as of April 2025. The company now publishes regular reserve reports and works closely with global regulators to improve trust and compliance.
What Is USDT Used for?
Tether (USDT) is primarily used as a stable digital currency that mirrors the value of the U.S. dollar. It serves multiple purposes in the crypto ecosystem:
• Trading: USDT is the most commonly used stablecoin for buying and selling cryptocurrencies. Its stable value makes it an ideal base pair for spot and futures trading.
• Hedging: Investors use USDT to protect against market volatility by parking their assets in a non-volatile token.
• Payments & Transfers: USDT enables fast, low-cost cross-border transactions without the need for traditional banks.
• DeFi & Yield Farming: It's widely used in decentralized finance for lending, borrowing, and earning yield through
liquidity pools.

You can send USDT via wallets or exchanges like BingX, using networks such as Tron (TRC-20) or Ethereum (ERC-20), depending on speed and fees.
Why Is USDT Popular Among Traders and Investors?
Tether (USDT) is popular because it offers price stability in a highly volatile crypto market. Since USDT is pegged to the U.S. dollar, it acts as a safe haven during market downturns, allowing traders to move quickly between cryptocurrencies and a stable asset without converting back to fiat.
It’s also widely accepted across exchanges and DeFi platforms, making it a universal trading pair. With fast, low-fee transactions on blockchains like Tron and Ethereum, USDT is ideal for everything from spot and futures trading to lending, borrowing, and remittances. This combination of stability, liquidity, and utility makes it a core asset in nearly every crypto portfolio.
What Blockchains Support Tether (USDT)?

BNB Smart Chain (BEP-20), Polygon,
Avalanche,
Arbitrum,

How Does USDT Differ From Other Stablecoins, Like USDC?
USDT and
USDC are both stablecoins pegged to the U.S. dollar, but they differ in
issuer transparency, adoption, and reserve management. USDT is issued by
Tether Limited, while USD Coin (USDC) is managed by
Circle (in partnership with Coinbase). USDC is often seen as more transparent, providing regular audits and real-time reserve disclosures. In contrast, Tether has faced scrutiny in the past but now publishes quarterly reserve reports and maintains strong market dominance.
USDT is also more widely used in trading and cross-border transfers, with a larger market cap and support across more blockchains. Meanwhile, USDC is more common in regulated DeFi applications and among institutional users due to its U.S.-compliant structure and clearer reserve backing.
Is Tether's USDT Safe and Fully Backed?
Tether (USDT) is designed to be fully backed, with each token representing one U.S. dollar held in reserves. Tether Limited claims that USDT is supported by a mix of assets, including U.S. Treasury bills, cash equivalents, and secured loans. The company publishes quarterly assurance reports to provide transparency into its reserve holdings.
While USDT is widely used and trusted across the crypto industry, it has faced past scrutiny over its reserve practices and regulatory compliance. In recent years, Tether has strengthened its transparency and now collaborates with law enforcement and regulatory agencies globally. For most users, USDT is considered safe for trading and transactions, but it's always smart to monitor official updates and reserve reports for added assurance.
How to Store USDT Tokens Securely
To store USDT securely, you should use a
reliable crypto wallet that supports the blockchain your USDT is on (e.g., ERC-20, TRC-20, BEP-20). Here are your main options:

Ledger or Trezor store your USDT offline, protecting it from hacks and malware. This is the safest option for large holdings.

MetaMask, and Atomic Wallet allow you to store USDT on your phone or desktop. Make sure to back up your recovery phrase and use strong passwords.

• Consider using a
cold wallet for long-term storage and a
